Because the atoms of the filament convert the energy into light energy through a reaction of the electrons, though it does also emit thermal energy. When the current passes through the filament, it excites the atoms and most specifically the electrons (the higher the energy content, the further away they orbit the nucleus of the atom) and makes them vibrate, which in turn causes the electrons to move further afield as they absorb the energy. This causes the radiation of light.
This is why filaments do not need electricity to work, merely a significant transference of energy.
No, a light bulb is not an electromagnet. A light bulb contains a filament that produces light when current flows through it, whereas an electromagnet is a device that produces a magnetic field when current flows through a coil of wire.
It is a conductor, but the filament is a resistor : as current flows through the filament, some of the energy is released as heat and light.
When an electric current flows through the metal filament of a light bulb, electrical energy is converted to heat and light energy, producing the illumination that we see as light. The filament heats up due to the resistance to the current passing through it, causing it to emit visible light.

The filament is a thin wire made of a material that produces light when electricity passes through it. It heats up and emits light when an electric current flows through it in an incandescent light bulb.

The filament is a thin wire made of a material that produces light when electricity passes through it. It heats up and emits light when an electric current flows through it in an incandescent light bulb.
The electrical current that flows through the metal filament of a light bulb is in the form of electrons. As the electrons pass through the filament, they encounter resistance, which causes the filament to heat up and emit light. This process converts electrical energy into light and heat energy.
Electrical energy to heat and light.
The filament in an incandescent light bulb is responsible for producing light when electricity flows through it. It heats up and emits light as a result of the electrical current passing through it.
To light up, the bulb needs an electrical current flowing through it. This current is typically provided by connecting the bulb to a power source, such as a battery or outlet. Once the current flows through the bulb's filament, it heats up and produces light.
The current causes heat. The heat is high enough to radiate energy in the form of visible light.
